as you can see , by using ((file property : tags)) I can avoid using tags twice or more and avoid waste of (time , energy & headache)
For the [wikilinks] I still couldn’t find any solution
I still encourage obsidian team to implement color change to Gray of used tags or links .
file property is a temporary option and it is still bothering
for example when i scroll down to tag13 after selecting tag13 the window which is showing the tags scrolls up to tag2 and again I have to scroll down and this makes me lose the thread of the where i was and ….
anyways , i thank obsidian team for such a great app .
